description="
libmnl is a minimalistic library oriented to Netlink developers.

There are a lot of common tasks in parsing, validating, constructing
of both the Netlink header and TLVs that are repetitive and easy to
get wrong.  This library aims to provide simple helpers that allows
you to re-use code and to avoid re-inventing the wheel.
